Substitute Part Grouping Explanation

Substitution eligibility for the UPJ1J331MHD1TO is determined by the following critical parameters:

Capacitance: 330 µF (exact match required)
Voltage Rating: 63 V (exact match required)
Tolerance: ±20% (exact match required)
Lead Spacing: 0.197" (5.00 mm) (exact match required for PCB compatibility)
Package Type: Radial, Can (exact match required)
Mounting Type: Through Hole (exact match required)
Polarization: Polar (exact match required)

All identified substitute parts meet these core electrical and mechanical parameters. Variations in impedance, ripple current ratings, lifetime temperature specifications, and product status are secondary considerations that may influence selection based on application requirements.

Engineering Selection Recommendations

Direct Equivalents (Nichicon Series)

UPJ1J331MHD and UPM1J331MHD1TO are direct electrical equivalents to the main part. Both maintain identical capacitance, voltage, tolerance, and mechanical dimensions. The primary difference is packaging format: UPJ1J331MHD is supplied in Bulk, while UPM1J331MHD1TO is supplied in Cut Tape. UPM1J331MHD1TO carries AEC-Q200 automotive qualification and is suitable for automotive applications. Both remain classified as Not For New Designs.

Active Product Alternatives

860080778021 (Würth Elektronik WCAP-ATLI series) and MAL214638331E3 (Vishay 146 RTI series) are active products with current manufacturing status. Both meet all core electrical and mechanical substitution criteria. The Würth part offers lower impedance (45 mOhms) and higher ripple current capability at high frequency (1.87 A @ 100 kHz). The Vishay part provides extended operating temperature range (-55°C ~ 125°C) and lifetime rating (5000 Hrs @ 125°C), with AEC-Q200 automotive qualification.

Selection between active alternatives depends on application thermal requirements and ripple current demands. For general-purpose applications within the -55°C ~ 105°C range, either active substitute is suitable. For elevated temperature environments or automotive applications requiring AEC-Q200 compliance, MAL214638331E3 is preferred.

Frequently Asked Questions (FAQ)

Q: Can UPJ1J331MHD1TO be directly replaced with UPJ1J331MHD?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging: UPJ1J331MHD is supplied in Bulk format while UPJ1J331MHD1TO is supplied in Cut Tape. PCB layout and circuit performance remain unchanged.

Q: What is the difference between Nichicon UPJ and UPM series?

A: The UPM series (UPM1J331MHD1TO) includes AEC-Q200 automotive qualification and lower impedance (49 mOhms vs. 72 mOhms). Both series share identical capacitance, voltage, and mechanical specifications. UPM is suitable for automotive applications; UPJ is for general purpose.

Q: Are the active products (Würth and Vishay) suitable replacements?

A: Yes. Both 860080778021 and MAL214638331E3 meet all core electrical and mechanical parameters. Both are ROHS3 compliant. The Würth part offers superior high-frequency ripple current performance. The Vishay part provides extended temperature range and lifetime rating at elevated temperature.

Q: Does switching to an active product require PCB redesign?

A: No. All substitute parts maintain identical lead spacing (0.197" / 5.00 mm), package type (Radial, Can), and mounting type (Through Hole). Direct PCB compatibility is maintained.

Q: Which substitute is recommended for new designs?

A: For new designs, select from active products: 860080778021 (Würth Elektronik) or MAL214638331E3 (Vishay). Both have current manufacturing status and long-term availability. For automotive applications, MAL214638331E3 with AEC-Q200 qualification is preferred.

Q: What is the impact of impedance differences between substitutes?

A: Lower impedance improves high-frequency ripple current performance and reduces voltage ripple. The Würth part (45 mOhms) provides the best high-frequency performance. For applications with stringent ripple current requirements at frequencies above 10 kHz, the Würth part is advantageous.
